A 3D printer in every home? These guys think so

Developers at the Vienna Institute of Technology have engineered what they say is the world's smallest printer capable of producing three-dimensional reproductions. The prototype printer, which weighs 3.3 pounds and is about the size of a milk carton, uses a synthetic resin in place of ink that is capable of producing hardened sheets just a twentieth of a millimeter thick. The team says the goal of the project is to make way for a viable consumer-priced 3D printer.
